Why do tournaments matter when this is based on skills, not how many tournaments you've won or played? Just because you haven't seen players like Janne perform well against good players doesn't mean others haven't. There are more opinions than just you're own, if you haven't seen Janne play against good people, the converse argument can be used, i.e. you have no basis to say he is bad just as you have no basis to say he is good.
